v 4 This invention relates to refrigerators for cooling bybrine and has forits object to provide a simple and lefficient refrigerator of Y this kind. f In` known refrigerators'operating on the cold brine shower system, perforated horizontal partitions in a refrigerating chamber for allowing cold brine shower are not arranged so as to always contain some coldl brine on the partition and allow rapid circulation of cold brine. The cold brine shower can not, therefore, be continuous and uniform throughout the whole area of each partition, and accordingly the refrigerating effect is inefficient, so that the refrigerators of this kind are not ingeneral use.

According to this invention each partition is formed as a perforated tray provided with one or more overflow openings which' are raised above the level' of the tray so that the brine must accumulate to a certain d-epthon the tray before it can overow on to the next tray below, and means are provided for ensuring that brine overflowing from an upper tray cannot pass directly into the overflow opening or openings of the next tray below. Thus in addition to the shower of brine falling continuously on to an article in one tray through the perforations in the tray above 1 there is a continuous circulation of brine over the bottomof the articles and efficient refrigeration is ensured.

The invention will be better understood by reference tothe accompanying` drawing in which: Y

Y Fig. 4 is a vertical section on line IV-IV of Fig. 3.

Fig. 5 is a perspective view of a frame for supporting a partition tray. l

VReferring now to the drawing, a refrigerating chamber l is-divided into several compartments 2 by meansl of horizontal lpartition trays 3. The top compartment and the i Vcharge pipeV 8 leading to the sourceor any bottom compartment maybe used for a' re'- frigerant inlet space and a refrigerant outlet space respectively, whilst the intermediate compartments may be used for storage spaces. Each compartment for storage space may be provided at one side with a water-tight door for access of articles, lsaid door being indicated at 4 in Fig. l and being hinged and adapted to be tightly closed by means of bolts 5 and wing nuts by way of example. Cold brine for refrigerant is delivered into the refrigerating chamber at its top through ya delivery pipe 7 from a source-(not shown) and is Vdischarged at the bottom to a dislsuitable place. l i

Each partition trayf3 is provided, with a number Vof small perforations 9 unformly disposed throughout the whole area, through which cold brine is allowed to shower, and is alsofprovidedadjacent a side wall or side walls of the refrigerating chamber 1 with one or more openings 1Q for overflow ,of superfluous cold brine which is more than the'perforations can kallow to pass through. The part l1 of the partition tray 3, where the openinglO is formed is raised up to suitable height asseen in Figs. l and 2,V so that cold brine may be Vcontained in the partition tray up tor` thelev'elfaccording to the height of the raised part 11 havingJtheo-pening l0. Suitable provision is 'made for the arrangement of the Y openingin such position as toprevent cold Y.

brine flowing downwards Vthrough the opening from passing by 'the compartment direct- .85 ly underthe openingwithout flowing inV the next partition tray. ln Fig. l, the openings 1 0 are arranged at opposite ends in twojconsecutive partition trays. In Fig. 2,.suitable `deflectors as indicated .at'l2 and l2 arel pro- 90 Vvided'below the openings, whereby the cold brine is deflectedV laterally so as tol flow in 'the next partition tray, without making direct communication with the openings of the next partition tray.' j

" Fig. 3 illustrates a modificationv of thelinvention which isV .designed for 'enabling'the partition trays to be adjusted .soas tobe al-v ways maintained in h'orizontal'position when i, Y ai ship such as fishing boat equipped with a re- 10 frigerator according to the invention lists to one side due to unbalanced loading of cargo on board to cause the partition trays in the refrigerating chamber to incline from their horizontal position.

In Fig. 3, rear supports 13 consisting of plate like members for carrying frames 14 for supporting the partition'trays are attached at either side lof the refrigerating chamber and adjacent the back wall of the chamber, and are provided with a number ofV lateral pins l5 arranged in pairs and projecting horizontally and inwardly in opposite direction for pivotally carrying the rear ends of the frames for supporting the partition tray.

Front supports 16 consisting of plate like members for carrying the frames for supporting the partition trays arel arranged for vertical adjustment at either side of the refrigerating chamber and near the front wall of the chamber. The plate-like supports 16 are provided with a number of lateral pins 17 arranged in pairs and projecting horizontally and inwardly in opposite direction for carrying the front ends of the frames 14 and slots 18 for receiving lateral guide pins 19 secured to the side walls of the refrigerating chamber.

To the upper end of the front supports are welded rods 2O which extend upwardly through the top wall of the refrigerating chamber. To the upper ends of these rods is connected a bar 21 having at its middle pointa threaded hole 22 for receiving ascrew 23 carrying a handle 24 which is suitably invention provides an improved refrigerator" of cold brine shower system, whereby the continuous uniform shower and rapid circulation of cold brine can be ensured, so that the ei'iciency of the refrigeration is considerably improved.

I-Iaving now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I claim:

1. A. refrigerator of cold brine shower .type comprising a refrigerating chamber having an inlet at the top and an outlet at the bottom for cold brine, superposed partition trays arranged horizontally in the refrigerating chamber and provided with a number of small perforations for allowing cold brine shower and openings for delivering superfluouscold brine from one partition tray to the next lower partition tray and preventing the cold brine flowing downwards from an upper partition tray on the next lower partition tray from directly passing into the overflow openings of the last mentioned partition tray Vthe greater part of Vthe cold brine coming down from an upper partition tray being received in the neXt lower partition tray. Y

2. A refrigerator according to claim 1 characterized by the provision of means for adjusting the partition trays so as to maintain the latter in horizontal position when the refrigerating chamber become inclined.

In testimony whereof I aix my signature.

Each frame 14 for supporting the/partitiontray is built up of angle bars as shown in Fig. 5 and is provided with angle pieces 25 attached under the rear ends of side angle members 14 and having slots l26 for receiving the rods 15. The frames 14 are carried on the front and rear support plates 13, 16 with the rear endsresting on the pins 15 engaging with the slots 26 of the angle pieces 25 and with the front ends resting on the pins 17. With this construction, the front support plates 16 can be movedvertically by `m-eans of the handleV 24 and accordingly the partition trays on the frames 14 can be ele vated or lowered at the front end to maintain the partition trays in horizontal position,

when `.the refrigerating chamber becomes inclined.

The articles to be stored are preferably put on suitable spacersV 27 arranged on the partition tray, so that cold brine may freely circulate under the articles. j,

In order to facilitate the inspection of the interior of the refrigerating chamber, suit able lamps and peep holes (not shown) are preferably arranged in ,thel walls of the refrigerating chamber in'linown manner.

d Fromthe foregoing, it will be seen that the
